Maize thresher has played a great role in agricultural production, ensuring a bumper harvest of grain production, farmers can not do without it. However, due to the type of motor thresher is too complicated, too many production sites, there are some models of imperfect, unsafe and reliable, poor manufacturing quality, coupled with the use of farmers in the lack of knowledge of safe operation, resulting in personal injury or death Often happens, which has brought tremendous suffering and losses to farmers. Without effective measures, it will surely seriously affect agricultural production.
